Is there any sort of water chiller to keep the temp stable at a point which will not cause condensation and damage components so I can avoid insulation on everything?

Ideally it will be a box to run my water through and get it back at around 15C ? (I am not sure what is safe for naked tubes)

cheers
 
i no u can do it just not sure how and whats needed could try xs forums as there more tuned to this sort of thing ??

Calculate your likely case heat and you may be able to calculate your dew point. If the water temp is below this temperature, you will get condensation on the outside of the tubing unless it is insulated.

So, before anything else, I would suggest you look into what a water-chiller is likely to cost you. There's one on fleabay for under £30 at the mo (pick-up only from Oxfordshire) but it uses >300W so expect to pay a fair bit to power such a system. And most are designed for chilling water that has only been raised slightly above it's output temperature by air-contact and some chilly fish. Whether such a device can cope with >100W being dumped into the water, I don't know, nor do I know how loud such a thing would be. Looks like I don't know a lot!

But what I do want to know is why? Why do you think this is a good idea? What makes you think you need to cool the water that low? And have you done any research into this?
 
I have normal water cooling for over a year now, and I was thinking how to improve the situation.

I thought of this idea to create some sort of a dual loop with TECs. Loop 1 will run through the components and loop 2 will run thorugh the TECs to chill the water. The idea is to develop some sort of "balance sensor switch" to turn the TEC on if the water temp >= dew+5 and off when water == dew.

This assumes the TECs are made to be used as relays and be switched on/off all the time. (a simple circuit, thats all i can do at least :p)

Reason is, experimentation basically :)
 
Rad I would imagine, cooled loop and hot loop.

Prototype here.

Eureka! Why has no-one ever suggested this before?! It's so obvious and we've all been wasting our time and money building closed loops when all we had to do was waste thousands of gallons of water needlessly!

Click to expand...

to be fair, (ignoring the complications of doing that), it wouldnt cost you anything because the mains is capped at like 180 pounds a year.

i would also like to know the answer to cooling the water, although i would think 20 -25degrees is good... so a small fridge style cooler, which will fit ontop of reservoir... (heat generated by the cooler is irrelevant if it doesnt mess up case temps, or is outside)...

hard to judge because no1 with water, when posting core temps, posts the water temps, so i cant tell how efficient water cooling is
 
Tec's, as a rule, are a waste of time and effort. You would be much better off going water cooling or Phase. A chiller will need insulating at all times, because unless you are in an air conditioned temp controlled room, the ambient temp will fluctuate too much.
